You can keep up with this challenge if you keep communicating with others. My big tip I found was to eat 70% of all my calories for the day before 3 or 4pm (dinner at lunch) then eat lightly or have a really nutritious shake with lots of fibre in it around 7:30 then NOTHING after 8 pm. I lost 4 pounds the first week I did that. It's hard to do if you are having a hectic day and can't eat a big meal by 3 or 4 but whenever you do it really works!

I found that the best tip that I could have ever used was really simple and it is working for me. I was told to eat breakfast like a King, Lunch like a Prince and Dinner like a Pauper. And it really has kicked my energy into high gear. I know that you can stick with this. Just stay focused and remember we all have set backs, It is continuing on that determines if you succeed after having a set back.
Best of luck to you.
